[S32K324] how to set ethernet VLAN ID in S32DS?

[Ethan_L]

Hi community,

I want to set ethernet VLAN ID on S32K324, but I can not find any information in LWIP example and S32DS peripherals UI.

Is there any example or document about how to set ethernet VLAN ID?

Thanks,

Ethan.

Hello @Ethan_L 

To send a VLAN frame, you can add VLAN tag into the frame array before calling Ethernet frame sending service. Something like below:

VlanTag[0U] = 0x81U;    /*TPID = 0x8100 */

VlanTag[1U] = 0x00U;

VlanTag[2U] = 0x00U;

VlanTag[3U] = 0x05U;

/* add vlan tag */

for (frameByteIdx = 12U; frameByteIdx < 16U; frameByteIdx++) {

        txBuff.data[frameByteIdx] = VlanTag[frameByteIdx%12U];

}

status = Gmac_Ip_SendFrame(instance, ring, &txBuff, NULL_PTR);

Best Regards,
